Abstract

We discuss the possibility of loosely bound states near the charm threshold in the charmed-particle and antiparticle system such as {Mathematical expression}, etc. An explicit calculation shows that the S- and P-wave states exist in the {Mathematical expression} system with reasonable values for the parameters of the interaction. These bound states may be very close to threshold with large sizes (r.m.s.≳1 fm). Characteristics of these molecularlike states and their relationship with the quark model {Mathematical expression} bound states are also discussed.
